AMD has three motherboard chipset nomenclature- X, B and A series. As you’d expect, the release of AMD A520 motherboards is inevitable. An industry source suggests the all-new low-budget tier chipset will be available in September. It is not surprising news, to be honest. But it looks like the A-series will be pushed harder towards low-budget gaming PCs and general/ HTPC segment.
The progress with AMD so far…
These might be accompanied with the Ryzen 4 Renoir APUs. While the new Matisse refresh variants will be out with the B550 motherboard in June. AMD did announce about its conditional support with the Ryzen 4000 Zen 3 CPUs on the B450 and X470 chipsets. Though I am sure AMD would like to push A series chipsets more than before.
Personally, I am curious to know about its price brackets and offerings since B550 motherboards are said to start at 100$. Tier 1 motherboard makers like Asus said to have multiple variants- including under its well-known sub brandings. Some of the variants are Prime A520M-A, the Prime A520M-E, and the Prime A520M-K. It also has TUF Gaming A520M-A and A520M-Plus.
The choice of words from AMD…
Understandably, these motherboards do not support PCIe 4.0 lanes. Maybe AMD wants to pair these with Ryzen 4000G/GE and Pro APUs. But in its introduction page, the company claims B550 for everyone. If that was the case, there wouldn’t be an asterisk next to the words “Ready for 3rd Gen AMD Ryzen™ processors and beyond.*. It is extremely likely PCIe 4.0 will not work when Ryzen 4000 APUs are paired with B550/ X570 chipsets, let alone the upcoming A520 motherboards. AMD’s choice of words sometimes puts them in a soup when they said the upcoming Zen 3 platform won’t work on the B450 and X470 platforms. Clarity is the key. PCIe 4.0 is not for the graphics card, but the NVMe PCIe 4.0 M.2 drives which is now widely available and getting cheaper by the generation. AMD has been advertising these NVMe drives in their own page.
While BIOS ROM size issue is a real thing, its marketing lingos leaves some bad after taste. A solution was devised, but with major caveats and limitations, the absence of BIOS rollback to retain Ryzen 3000 and below support is one of them.
